DESCRIPTION

The Microchip Technology Inc. 25LC320/25C320

(25xx320

) are 32K bit serial Electrically Erasable

PROMs. The memory is accessed via a simple Serial

Peripheral Interface (SPI) compatible serial bus. The

bus signals required are a clock input (SCK) plus sep-

arate data in (SI) and data out (SO) lines. Access to the

device is controlled through a chip select (CS) input.

Communication to the device can be paused via the

hold pin (HOLD). While the device is paused, transi-

tions on its inputs will be ignored, with the exception of

chip select, allowing the host to service higher priority

interrupts.

*25xx320 is used in this document as a generic part number for the 25LC320/25C320 devices.
